Value Collection C703166 Hex Head Cap Screw 7/16-14 Grade 8

Product Description

The VALUE COLLECTION C703166 is a Grade 8 steel hex head cap screw intended for high-strength fastening applications. With a 7/16-14 UNC thread and a 2.5-inch length under head, this partially threaded fastener delivers the clamping force and shear resistance required in demanding mechanical and structural assemblies. The uncoated finish is suited for applications where post-installation coating or galvanic considerations are a factor. Produced to ASME B18.2.1 dimensional standards, it provides consistent head geometry and thread form for reliable performance in production and field service environments.

This screw is appropriate for general industrial, mechanical, and structural applications where Grade 8 tensile strength is specified. Partial threading is standard practice for fasteners in this length range, keeping the shank section intact for load-bearing joints and preventing thread engagement in the grip area. Typical users include maintenance technicians, millwrights, and fabricators working on equipment assemblies, frames, and heavy-duty machinery. This SKU is packaged in quantities of 50, making it practical for job-site use or shop-floor restocking.

Key Features

• Grade 8 steel construction for high tensile and proof load strength
• 7/16-14 UNC thread for broad compatibility with standard inch-series nuts and tapped holes
• Partially threaded shank per standard practice for this length, maintaining grip integrity under shear loads
• Uncoated finish suitable for secondary coating or use in controlled environments
• Manufactured to ASME B18.2.1 for consistent dimensional accuracy
• Sold in 50-piece packages for convenient job lot use

Compatibility

Designed for use with standard 7/16-14 UNC hex nuts, washers, and tapped holes conforming to inch-series thread standards. Suitable as a direct replacement or specification-match fastener wherever ASME B18.2.1 Grade 8 hex head cap screws are called out.

Installation Notes

Installation should be performed by a qualified technician familiar with fastener torque specifications for Grade 8 hardware. Always ensure mating threads and bearing surfaces are clean and free of debris before assembly. Use a calibrated torque wrench and follow the applicable fastener torque table for the joint material and lubrication condition. Do not reuse fasteners that show signs of thread deformation, corrosion, or prior overloading.
